I'm replacing the router here in the BlueTower today, as we've been getting very spotty wi-fi coverage in the living room downstairs. It may turn out we need a repeater somewhere in the middle, but the new unit should have better coverage, so maybe not. Since it seemed like time to get a dual-band router because there are so many devices on the network, and a couple of them can take full advantage of both bands, so this seemed like the logical first step.
